Progress towards Studying the Neon Film Morphology on High T_c YBCO Resonators

Trapped electrons on cold, solid neon has shown to be a viable alternative solid-state qubit platform, demonstrating impressive coherence times. Due to a lack of characterization techniques, the growth kinetics of neon film on to the microchip has not yet been well understood. We look to characterize the uniformity, conformality, and solidification dynamics of the neon thin film with high T_c, YBCO microwave resonators. These resonators have frequencies ranging from 1 to 8 GHz and retain their superconducting properties up to 70 K, well past the triple point of neon. In this talk, we describe the design and fabrication of such resonators, and preliminary results of microwave measurements with and without neon coating. This investigation is the first step towards a clear picture of neon deposition on microwave resonators for future scalable electron-on-neon systems.
